As the fry of litforaUs, which assumes at times the 

 colouring and general aspect of this species, is occasionally 

 marked as such in the cabinets of collectors, we may 

 observe that even in that early stage it is a more solid 

 shell, is peaked and somewhat produced at the base, and 

 exhibits a wider confluence of pillar and outer lip. 



This little shell has a rather obliquely subglobose form, 

 is rather broader than long, thin, a little transparent, 

 slightly or scarcely glossy, of an orange-brown, loosely 

 reticulated by rufous lines, and is apparently smooth ; 

 numerous longitudinal wrinkles, however, may be discerned 

 by the magnifying glass, and a lens of high power 

 discloses, likewise, faint traces of densely disposed spiral 

 striulse. The spire is very short, occupying only the 

 sixth or even the fifth of the total length ; it consists 

 of two whorls and a half, that are separated by a fine 

 but profound suture, increase rather quickly in length, 

 and terminate in a small but bluntish apex. Although 

 not ventricose, they are convex, but are little elevated, 

 and very gently shelving. The body is very ample,
